Abstract This paper presents the influence of the type of filtration beds, used in swimming pool water treatment systems, on the quality and the possibility of reuse of washings. The research covered 4 pool cycles with sand, sand and anthracite, glass and diatomaceous beds. The degree of contamination of washings was assessed on the basis of physical, chemical and bacteriological tests. The possibility of washings drainage into the natural environment was considered, and the results of the research were compared with the permissible values of pollution indicators for wastewater discharged to water or ground. A direct management of washings from the analysed filters proved impossible mainly due to the high content of TSS (total suspended solids) and free chlorine. Washings were subjected to sedimentation and then the supernatant was stirred intensively. As a result of these processes, the quality of washings was significantly improved. This allowed planning to supplement the pool water installations with systems for washings management.

Theobroma Cacao L

Research has been carried out to improve the quality of the yellow pool water. The water is used as a source of clean water for the academics of the Politeknik Negeri Padang, so it needs to be improved in accordance with the quality standards of clean water, and is suitable for daily use. The adsorption process was carried out using activated carbon of Theobroma cacao L. shells which was carbonated at 400oC for 1 hour and activated with H3PO4. Characterization of functional groups using Frontier Transform Infra Red (FTIR), and morphology of surface  using Scanning Electron Microscopy (SEM). The quality of clean water standard analyzed is turbidity, Total Dissolved Solids (TDS), color, Total Suspended Solids (TSS), and Fe content. Functional group analysis exhibits that the activated carbon produced has a pattern of absorption with O-H, C-H, and C-O bond types. At the optimum condition of the activation process, a good adsorbent is absorbed in pool water purification at a flow rate of 5 mL/min with a mass of 2 grams. The analysis showed an efficiency decrease in turbidity value of 67%, Total Dissolved Solids (TDS) 71%, Color 97%, Total Suspended Solids (TSS) 86%, and Fe content 38%. Surface morphology of activated carbon showed the presence of pore cavities, and after the filtration process the cavities became saturated. This shows that there has been an absorption by activated carbon, so that the water becomes clear. Activated carbon of Theobroma cacao L.shell is very effective in the process of purifying pool water into clean water and fulfilling clean water standards, so it is suitable for  are used.

Groundwater samples collected at different locations in and around Namakkal were analyzed for their physicochemical characteristics. Ten locations of groundwater samples were collected and studied for every two month for the period June-2007 to December-2007. The present investigation is focused on the determination of physicochemical parameters such as temperature, taste, turbidity, electrical conductivity, pH, hardness, total solids, total dissolved solids, total suspended solids, chlorides, sulphate, nitrate, fluorides, dissolved oxygen, sodium, potassium andE.colibacterium. Groundwater suitability for domestic and irrigation purposes was examined by using WHO and BIS standards, which indicate the groundwater in a few areas, were not much suitable for domestic and agriculture purposes. Thus the objective of this study is to identify the quality of groundwater especially in the town and near by town where groundwater is used for domestic and agriculture purposes is discussed.

The volume of FGD wastewater of coal-fired power plant is very large, and it contains a large number of inorganic salts, suspended solids and heavy metals, the directly discharge of wastewater will cause a lot of pollution to the environment. This paper selects the FGD wastewater of Baoding power plant as a research object, it is taken experimental study by physical and chemical methods, the harmful substances in the wastewater are removed, so the quality of FGD wastewater achieves the national emission standards of sewage.

Currently, attention is paid to the intensification of the process of natural and wastewater treatment, improvement of technology, development of new effective methods of intensification of water treatment. This will simplify the existing technology of water treatment, reduce labor-intensive processes of preparation and dosing of reagents, reduce the cost of operating treatment plants, increase their productivity, improve quality and reduce the cost of treated water. Treatment of water with a modified coagulant solution allows to increase the hydraulic size of the coagulated suspension. The strongest effect of the modified coagulant solution has on the hydraulic suspension size of 0.2 mm/s and less, i.e. the smallest and the suspension, which is difficult to remove, which creates conditions for more intensive sedimentation in settling tanks and improve the quality of water clarification and fed to fast filters. It has been experimentally determined that the treatment of water with a modified solution of aluminum sulfate coagulant should be performed when the content of suspended solids in the clarified water is up to 100–150 mg / dm3. The color of the clarified water during treatment with a modified solution of aluminum sulfate coagulant does not depend on the content of suspended solids and is 1.5-1.6 times lower than the color than when using a conventional coagulant solution. It is established that the use of a modified solution of aluminum sulfate coagulant in water purification can reduce the residual aluminum content in clarified water by an average of 50-60%. The results of researches of the modified solutions of reagents which are used at preparation of drinking water are presented. It is established that water treatment with a modified solution of aluminum sulfate coagulant allows to improve the quality of drinking water preparation by suspended solids, color, reduce the content of aluminum salts in the clarified water, thereby increasing the environmental safety of drinking water.

The University Center of Biological and Agricultural Sciences (CUCBA) of the University of Guadalajara receives approximately 5700 students, and 1500 of the academic, administrative and visiting staff. The CUCBA is research oriented, therefore, large amount of chemical waste and microbial load is generated by health services. There are two sources of water supply that provide quality drinking water to the student population and two water treatment plants that process the wastewater produced. The objective of this study was to evaluate the physical chemical and bacteriological quality of the water from the sources of supply, storage tanks, distribution network and principals points of use as an area of food and drinkers, as well as the wastewater emitted in triplicate. The water quality index was calculated, and regular values of the water quality of the 10 sampled points were found, and it is noted that, the sampling points with the lowest quality index were the water that leaves the plants of Water treatment, therefore, is not being accomplished with proper water purification.

Sand Filter

In an attempt to improve the quality of the agricultural drain in Egypt for its reuse again in the irrigation, low cost solution such as sand filter along with/ without other filtration media have been used in this research, As a result of that, pilot plant of sand filter mixed with other filtration media was tested for its ability to improve the sand performance in removing the suspended solids and organic matters from agricultural drain water of the Belbeis drain (in Sharkia governorate in Egypt). Only sand compared with sand with sponge and sand with Liyan Nanfang activated carbon (L.N.A.C) have been tested to find the optimum mixing sand/ medium ratio &optimum infiltration rate. The work has been done on four runs. It was found that sand mixed with sponge gave the best removal efficiency compared to that of the sand only and the sand mixed with L.N.A.C. The results presented that the concentration of CODt, CODsol and TSS was reduced from 125, 47 and 162 mg/l to 44, 34 and 28 mg/l respectively at optimum infiltration rate of 2 m3/m2/d for sand mixed with sponge.
